Just lost my fort due to a single lever not being pulled in time.
After having set out to collect every single item on the map and bring it to my gigantic stockpile underground, and trading to the orcs and dwarves for over 100 000 dwarfbucks, I get a demon siege. No problem, I pull the lever to close the main gate... except it doesn't close in time. In seconds, dozens of demons kill everyone in my military and start rampaging through the upper levels... which I have forbidden access to via a floor hatch. They get themselves killed in my trap corridor, and eventually flee... only to encounter two dozen werewolves coming towards them. They also get killed and leave, and just as I thought it was all over, it turns out that the giant cat demon leader is still hanging out all by itself and slowly working its way through the doors to get to the main stairwell.
Then a tantrum spiral hits because so many died.
This is disconcerting in itself, but then the demons come back and together with their leader massacre most of the fort. Interestingly, when only three people are left (a leatherworker, a brewer who decided to
take a nap in his room during the massacre and an insane lye maker moping over his lost relatives in his room), the demons leave again... everyone except the leader, who seems content to sit in the main stairwell and spook everyone trying to get past it. This results in the mayor-brewer constantly trying to get past it to eat, failing, and then trying again. Fortunately, I've activated the aquifer well-filling floodgate, and the hospital is slowly flooding. Too slowly, in fact...
Then 20 migrants arrive.
I don't know why, but they do. Four are legendaries.
They help rebuild the fort, and the elite pikedwarf even helps fight the demon lord to little avail. Adamantine helps, but she can't quite kill it, and soon most of the migrants are stuck in a side corridor trying to hide from the remarkably peaceful beast (it only fights in self-defense, and quite a lot of it is just "jumps away" and stuff...)...
Then an illithid siege comes.
Interestingly, after the frantic attempts to close the gates and doors that obviously fail, and the illithids start slaughtering everything... guess who's left? The original mayor, who survived again because he decided some butchering needed to be done. The only other survivors is an animal caretaker and an ecstatic mason, who apparently was so impressed by the five-minute long talk he got with the new mayor that it completely offset having to wade through knee-deep water rife with hundreds of dead bodies, blood, vomit, miasma and poison. Scary guy...
Then, of course, the mayor dies of thirst while butchering, and I get to watch the animal caretaker
almost managing to hide from the illithids, who once again decide to leave halfway through, when the last one spots him and chases him all over the stockpile and rooms before strangling him and leaving him for dead. He soon suffocates, and that's the end of it. Goodbye Riverlens
Hm... maybe I should try reclaiming...?
